Floppy Drive Connector
Clearly there is a Floppy disk interface, but not the usual one with 34 pins,
but one with 26 pins as you find in laptops. The table below show the comparison
between a normal floppy interface and CN13 together with the pins connected to
the I/O chip PC87309IBW/VLJ and the signal names.

uneven pins on fdd connector are ground signal.
pins 1,3,5 of CN13 are connected to each other on the main-
board and should supply the power for the drive.
pins 7,8,9,11 are unconnected.
pins 15,17,19,21,23,25 are VSS/ground signal.

Connect all pins straight through. So pin 1 on 1,...
Pin 1, 3 and 5 should act as the supply voltage pins, but they aren't connected
to a supply signal on the board.
On the backside of the board there is a spot to solder a
fuse: F2 1.1A/40V.
Activate the drive interface in two places in the CMOS setup:
In main screen I have set the `Legacy diskette A:' to
In the Advanced section there is the sub-menu `I/O Device
Configuration' and there the `Floppy Disk controller' needs to be set `Enabled'.
After a reset you hear the floppy
